Benchmark Dataset for the Voronoi Diagram of 3D Spherical Balls

1. Summary
This is a dataset to be used for the construction of the Voronoi diagram of 3D spherical balls (VD-B3). The dataset consists of sphere arrangements including general, anomaly, and extreme cases. The dataset also includes protein models downloaded from RCSB Protein Data Bank (PDB). The dataset can be used as a standard benchmark dataset to verify and validate the accuracy, efficiency, and robustness of the construction algorithm.

2. Dataset description
2.1. Sets of random 3D spherical balls within a spherical container: BALLCLOUD, BALLSMALLSET[1,10], VISUALSET (Vis-I-10). Hereafter a ball denotes a 3D spherical one.
2.2. Sets of random balls touching a reference sphere: EXTREMESET, VISUALSET (Vis-V-20, Vis-VI-6, Vis-VII-20)
2.3. A set of balls on a grid: VISUALSET (Vis-IV-60)
2.4. Sets of balls for anomaly case in Voronoi diagram: ANOMALYSET, VISUALSET (Vis-II-5, Vis-III-5)
2.5. A set of protein models downloaded from RCSB Protein Data Bank: PROTEINSET

3. File format
The integer of the first line denotes the number of balls. Each following line contains the definition of each ball with 5 fields in order: id (integer); x-, y-, z- coordinate of ball center (floating-point number); radius of ball (floating-point number). The floating-point number is represented up to six decimal places. Each file in BALLCLOUD, BALLSMALLSET, EXTREMESET, ANOMALYSET, VISUALSET follows the data format.

1. 摘要
本数据集用于三维球面沃罗诺伊图（Voronoi diagram，VD-B3）的构建任务。数据集涵盖通用、异常及极端场景下的球面排布，同时包含从RCSB蛋白质数据库（RCSB Protein Data Bank，PDB）下载的蛋白质模型。该数据集可作为标准基准数据集，用于验证构建算法的准确性、效率与鲁棒性。
2. 数据集说明
2.1 球形容器内的随机三维球面集合：BALLCLOUD、BALLSMALLSET[1,10]、VISUALSET（Vis-I-10）。下文所述“球”均指代三维球面。
2.2 与参考球相切的随机球面集合：EXTREMESET、VISUALSET（Vis-V-20、Vis-VI-6、Vis-VII-20）
2.3 网格排布的球面集合：VISUALSET（Vis-IV-60）
2.4 沃罗诺伊图异常场景用球面集合：ANOMALYSET、VISUALSET（Vis-II-5、Vis-III-5）
2.5 从RCSB蛋白质数据库下载的蛋白质模型集合：PROTEINSET
3. 文件格式
首行的整数表示球面的总数量。后续每行依次通过5个字段定义单个球面：球面ID（整数）、球心的x、y、z坐标（浮点数）、球面半径（浮点数）。浮点数保留六位小数。BALLCLOUD、BALLSMALLSET、EXTREMESET、ANOMALYSET、VISUALSET下的所有文件均遵循该数据格式。
